DUPLEX WIRE-NAIL MACHINE.

SPECIFICATION forming part of'Letters Patent No. 349,054. dated September 14, 1886,

Application filed June 9, 1886. Serial No. 204,618. (No model.)

To rtZZ whom it may concern: 1 The operating parts of my machine are sup- Be it known that I, Gnonens QURIN, having duly made oath of intention to become a citizen of the United States, residing at C- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Duplex Wire Tack, Nail, and Spike llfachines; and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which .it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of thisinvention is to provide an improved wire tack, nail, and spike machine for the manufacture of pointed and headed tacks and nails of any desired size and shape from a continuous piece of wire; and the invention consists of the improved machine hereinafter described.

In the accompanyi ug drawings, forming part of this specification, Figure 1 represents a side elevation of a machine embodying myinventiou; Fig. 2, asectiou on line to a, Fig. 3. Fig. 3 represents a plan view thereof, showing the two wires or blanks'as entering the rolling apparatus; Figs. 4, 4, 4", and 4-, respectively, a section on line aa, Fig. 5, and top and side views of-the fulcrum-stock; Fig. 5, an enlarged detail between the lines .r 00 and y 3 Fig. 3, with the detacher removed. Fig. 6 represents the adjust-able die-stock; Figs. 7, 7", and 7", details of the knife-levers; Fig. 8, a perspec tive of the hammer; Figs. 9 and 9, a plan and section of the rolling apparatus. Fig. 10 is a bottom view of the slide or feeding device; Fig. 10, one of the cranklevers; Fig. 11, one of the cams; Figs. 12, 12, 12', and 12, the diesharpening apparatus, and Fig. 13 the bridge.

A maehinefor the manufacture of wire nails should be simple of construction, embodying means whereby the working parts are readily adj ustable, an dthe means of adjustment should be readily accessible. The parts should be light and well'proportioued, but sufficiently strong to withstand the work and pressure required. These principles I have endeavored to embody inlay invention.

ported upon a suitable standard, D, which is provided with a camshaft, L, to which are keyed the several actuatingcams hereinafter described. The motive power is applied to the shaft by any suitable means.

In this duplex machine two wires or blanks are fed through a double series of guide-rolls, (marked R It, rcspectively,) one series being superposed above the other. The two middle rolls, 1' r, are laterally adjustable by means of the screws 1'. From these rolls the superposed wires pass to the slide S, which takes up and intermittently feeds the wires through the parallel wireways of the guide-block a.

The slide S, which is held upon the bar S by means of the spring S", Figs. 2 and 10, is provided with the radial shoulders s 8 between stud .9 which in turn is provided with an anvil,(notshown,) over which the two wires pass, one above the other. Two bell-crank levers, S S, as shown in Fig. 2, are pivotally connected'to the slide S. These bell-crank lewhich the feed-bar Q is held, and also with the The springs t t of the superposed levers press against the lug t", and thereby force the ends containing the chisels t t against the wires which are engaged by said chisels, and when the latter are carried forward the two superposed wires are simultaneously fed to the duplex pressure-dies b b, as clearly shown in Figs. 2 and 3. In their backward movement the levers readily disengage themselves and slide over the wires.

The duplex pressure-dies and their arrangement form a very important part of my invent-ion. These duplex dies (marked 2) and b) are horizontally adjustablein a verticallyadjustable die-stock, B, the latter being held frame D and clamped by means of the clampscrew p. This screw is provided with the angular lip p, as shown in Fig. 5, which, when the screw 11 is tightened, forces the die-stock B against the shoulder d of the frame, and thus securely clamps the same. The die-stock is vertically adjustable by means of the screw 0 as shown in Fig. 2. The two horizontal pressure-dies b b are guided within a dovetailed guideway of the die-stock B, and are provided with the serrated wireways b" b, which are a continuation of the wireways of the guide-block a, as clear] y shown in Fig. 6. These duplex dies-of which the one marked 1) is stationary, being adjustable by means of the screw 1), while the one marked L is actuated by the pressurelever -clamp the two wires in the ways b I), when the hammer F forms the two heads. The screws marked 1), pressing upon the key 1)", serve to clamp the die b and ease the movement of die Z within the guideway. The movement of the pressure-die b toward the die I) is regulated by means of the screw 1) of the lever P, the die b being movably connected thereto by means of a link} (I. The outward movement of the die is checked by means of the screw d. The wires, after leaving the pressure-dies b I), passing through the same in juxtaposition, are fed to a duplex point-cutting mechanisn1,con1- prising a set of duplex cutting-dies mounted within suitable knife-levers, the levers working pivotally within sockets of an adjustable fulcrum-stock, G, which is situated immediately in front of the pressuredies b b. The fulcrum-stock G, provided with a feather-fitting top, rests on either side on the frame D, working in the center upon the pin i of the slide 9, as shown in Figs. 2 and 4. The stock is provided with the elongated slots 9 g", pivotsockets g y, and the central socket, g", adapted to contain the pin i of the slide g. The two pivoted knife-levers M and M, provided with the studs m m, work within the sockets g y of the fulcrum-stock, being vertically adjustable therein, and rest upon the adjustable set-screws m m, which project into the sockets. Springs H H, attached to the top of the stock, and provided with small metallic buttons, exert a pressure upon the studs m m, and tend thereby to continually force them upon the adjusting'screws m m. By means of the slide 9 the fulcrum-stock may be carried forward or rearward, being pivotally connected to said slide, and by means of the pivot-pin i and socket g" the stock may be readily adj usted. The slide g is operated by means of a screw, 9, as will be readily understood by referring to Figs. 2 and 4 of the annexed drawings. The fulcrum-stock is set by means of the bolts on m, which are connected to the frame D and pass through the elongated slots g of the stock, being fastened on top by means of nuts. It will thus be seen that the knife-levers M and M are universally adjustable longitudinally by means of the slide g, the fulcrumstock G being pivotal] y connect-ed thereto vertically by means of the adj usting-screws Win and radially by means of the fulcrum-stock G. The knife-levers M and M, by the joint cutting action of which two points are simultaneously cut and two nails severed from the blanks, are peculiarly but gracefully shaped. The front or jaw stocks are provided with the adjustable duplex cutting-dies a a, while the rear or lever portion is provided with the cars a n and the rolls n a", which work upon journals that are held in position by suitable screws, as shown in Figs. 7, 7, and 7". The levers M and M are provided with the diverging hardened and tempered breasts m m", that serve as a guide for the upsetting die or hammer F.

The construction of the knife-levers form a very important part of my invention. It often happens that one or the other of the knifelevers tightly wedges into the blanks when cutting the points, so that the springsf orf, which are designed to force the levers into an open position, fail to perform their function. The hammer F, which plunges immediately after the joint cutting action of the knife-lever M M, would crush into the cutting-dies 11 a if it were not for the breasts m m, which the hammer strikes, forcing the lever or levers into the proper position. It also occasionally happens that the springs ff break, leaving the dies n a in the path of the hammer F. This would also result seriously ifit were not for the breasts m m, which the hammer ongages, and thus forces the dies out of its path. By this arrangement of the knife-levers the springsff may be dispensed with.

The duplex cutting-dies n 11, as shown in Fig. 7, are held in the jaws of the levers by means of the angular lips Mn and the screwplates a a.

The cutting-dies n n are adj ustablc by means of the screws 0 c, which are clamped by the pins 0 c and the set-serews c 0'. These dies are provided with two adjoining pyramidalshaped angular depressions, a n, the apices of which terminate at the cutting-edges a If of the dies, as clearly shown in Fig. 7 These dies at n are very carefully constructed, as it is very necessary that the cutting-edges of the two dies should exactly coincide; otherwise imperfectly-pointed nails will be formed. it. is also very necessary that the cutting-edges of the dies should accurately coincide with the wireways of the guide-block a and 01' the pressuredies 0 b. This is readily accomplished by means of the adjusting devices de scribed above.

In order to have one die precisely like the other, I employ the apparatus shown in Figs. 12,12,12", and 12, by which in clamping the dies at n in the angle-iron V and guiding a file, V, in the adjustable ways 0 '0 of the iron I am enabled to cut one die precisely like the other.

Adjoining the knife-levcrlll', working upon a suitable stud, is the pivoted pressure-level.-

P. .This .lever is similar in construction to the knife-levers, being provided with an antifriction roller and the ear p At the forward end the lever is provided with an adjustingscrew, 1), and set-screw 1f. The adj ustingscrew 9* is provided with a button, which is engaged by a connecting-link, d, that is pivotally connected to the movable duplex pressure-dieb, as shown in Fig. 5. The movement of the lever P in one direction is checked by means of the screw (1. The return motion of the knifelevers M Mand the pressure-lever P is accomplished by means of the springs f, f, and f, which bear against ears at the rear of the several levers. The cam-shaft L is provided with the cams E E E and the crankeccentric K. The outermost cam, E, is keyed to the shaft and operates the pressure-lever P. This lever is laterally oscillated by means of the cam E, which engages the roll of the lever, and thus forces the duplex pressure-die l), which is connected thereto, into open and closed position when the wires are feeding and when the heads are being formed. The duplex cams E and E engage the knife-leversM M, the hammer F, and the bridge K of the detaeher A. These cams are both rigidly keyed to the shaft L. The parts marked e e engage the rolls of the knife-levers, simultaneously opening and closing the same. parts marked e'c drop and raise the bridge la, imparting thereby the plunging motion to the detacher, while the parts markede c engage the lug f of the hammer F, forcing the latter against the spring F, but releasing the same at the proper moment when propelled by the spring F. The crank-eccentric K, to facilitate adjustment, is provided with apinion and pinion-rod It". To the and 7c" is at tached the adjustable pitman Z, that is connected by means of a universal joint, q, to the pivoted feed-bar Q. It will be seen that the parts marked K, Z, Q,and S constitute the adjustable feeding mechanism by means of which the length of the nails is regulated. The bridge It connects the arm A, which is adjustable therein and set by means of a set-screw, r, to the wooden or metallic spring A. This'spring is fastened to the frame D by any suitable means. The bridge k, riding upon the cams ee, imparts a plunging motion to the, arm A, which at each revolution of the c ams plunges downward and detachesthe finished nail from the blank.

The detacher, although not required until the nail is finished, forms, nevertheless, a very important part of the machine. It often happens, especiallywhen the dies become somewhat dull, that the nails are not entirely severed from the blank. As these hanging nails would interfere with the operation of the hammer F, it is very necessary that they should be removed, which is accomplished by means of this detacher A.

The hammer shown in Fig. 8 is provided with a suitable socket adapted to contain the Theshank of the removable duplex upsetting-die f which is held in the socket by means of a pin, f \Vhen square, round, or conical heads are to be made, the dief is provided with two suitable cavities adapted to simultaneously work the heads upon the two projecting. blanks. Centrally of its length the hammer is provided with the lugf This lugisengaged by the cams E E and forces the hammer against the spring F. At the proper moment the cams release the hammer, and it plunges forward, being guidedin the rear by the way D of the frame D and forwardly by the fulcrum-stock G and the knife-levers M M. At the rear the hammer is provided with the. movable saddlef, that engages one member of the spring F. ,The force of the spring F is regulated by means of the screw 0. The hammer is shown in its extreme rearward po' sition in Fig. 2 and in perspective in Fig. 8. The nail-head cavity may be in the upsettingdief or in the pressure-dies b I).

The operation of my machine is as follows: The pressure-lever P, which may be of any suitable metal, clamps the two superposed wires between the pressure-diesb b. The cams E E liberate the hammer F, which, propelled by the force of the spring F, plunges forward, upsetting the blanks, and thereby forming the heads upon two tacks or nails. At this moment the pressure-lever P recedes, and the wires are advanced the length of a nail by the slide S. The hammer now recedes to its normal position. At this moment the pivoted knife-levers M M are simultaneously engaged by the cams E E, forcing the dies or it upon the blanks, by the joint cutting action of which the two pyramidal points are formed. The levers then open, whereupon the detacher A descends, forcing the finished nails into a suitable receptacle. In the mean time the pressure-dies b b have again clamped the wires, the hammer again descends, forming the heads of the nails, and thus the operation is continued.

\Vith a slight modification of the construction three or more wires may be simultane ously fed into the machine. By changing the dies b b or the upsettingdie f, heads of square, round, flat, or conical shape may be formed.

My machines are preferably made in several sizes. The smallest machines, manufacturing nails from one-fourth to one-half inch in length, making two hundred and fifty revolutions per minute, are capable of turning out five hundred nails per minute. The machines manufacturing the larger size nails and spikes, from one and one-half to eight inches in length, are capable of turning out eighty spikes per minute.
